Remarks
The range and resolution are fixed for continuity tests. The range is 1 kΩ
(a 2-wire resistance measurement).
The meter beeps (even if beep is disabled) for each measurement that is
less than or equal to the continuity threshold (≤10 Ω), and the actual
resistance reading is displayed on the front panel.
From 10 Ω to 1.2 kΩ the meter displays the actual resistance reading with
no beep.
If the reading exceeds 1.2 kΩ, the meter displays "OPEN" on the front
panel (no beep).
The FETCh?, READ?, and MEASure:CONTinuity? commands return the
measured resistance, regardless of its value.
